At what point, though, Cherry, do you decide what is the 'alternate reality' and history? Afterall, the Great Pantheon has 'Agrippa Built This' carved in huge letters right across the front of it? I personally feel like I am 'progressing thru' a historical setting when I build these.....far more rewarding than just building the 'generic' baths and forums of RTW...which really were most often named by\for the person who built them. All of Rome's major highways were named after the Consul who built them, which is where 'Via Consularius' comes from. There is just so much more depth when you attach a 'human being' who really lived with something you build and see a picture of.
Examples:
Aurelian Walls
Trajan's Column
Arch of Constantine
Via Appia, was begun by Appius Claudius Caecus in 312 BC
Temple of Julius Caesar
Via Aurelia
Via Flaminia (220BC), It was constructed by Gaius Flaminius during his censorship (220 BC).
The list goes on and on.....
